Over a career in wine spanning two decades, Mark Castaldi has earned a reputation as a visionary leader and one of the most respected executives in the industry. As both estate director and CFO, Mark stewards every aspect of Acumen, dedicating his wealth of knowledge and experience to the goal of creating Napa Valley’s next great wine estate. With integrity and an unwavering commitment to excellence, Mark guides the Acumen team in its mission of crafting classically structured mountain-grown wines that are recognized for their vineyard-driven complexity and age-worthiness.

Mark discovered an affinity for agriculture and wine early in life and earned a Bachelor of Science degree in agricultural economics from the University of Nevada, Reno. He then went on to receive his master’s in agricultural business from Washington State University in 1984. After spending five years teaching finance, economics and business management at Cornell University, Mark worked the next decade in the food and beverage industry, where he specialized in long-term strategic planning, supply chain optimization, branding and distributor relationships with several large consumer packaged goods companies; namely Dole and Del Monte Foods. 

In 2001, eager to follow his lifelong passion for wine, Mark joined Beringer Wine Estates as a facility manager, where he gained invaluable hands-on experience in vineyard management, production, and winemaking. In the years that followed, Mark served as the general manager for Jackson Family Wines, the vice president, and general manager for Estancia Wines, COO and CFO for Schug Carneros Estate Winery and general manager for Sonoma Wine Company. He also established his own highly successful consultancy, where he worked with top wineries, including small and mid-sized family wineries. Prior to joining Acumen in 2019, Mark was the vice president of production and winemaking for Precept Wine.

At Acumen, Mark seamlessly blends his unique dual background in finance and operations to ensure the long-term vitality and success of both the vineyards and the winery. Though he has worked for some of the world’s largest wine companies, Mark relishes the opportunity to focus his talents at Acumen. “Because of how remote it is, Atlas Peak is still relatively unknown,” says Mark. “But those who know Napa Valley, recognize that it is one of the great regions for mountain-grown wines. From honoring the uniqueness of our terroir to the intimate way we farm our estate vineyards, our goal is to share our passion for Atlas Peak with the world, while establishing Acumen as the benchmark for the region.”

As winemaker for Acumen, Henrik Poulsen has a very clear focus: make wine that is an honest and joyous expression of the vineyard. Part of this preoccupation lies with his own winemaking philosophy, but it is equally a nod to the distinctive nature of Acumen’s organically-farmed vineyards on Atlas Peak. The high-elevation climate, volcanic soils and long growing season provide Acumen with fruit that has fully mature flavors while retaining complex structure due to naturally higher levels of tannin, a quality that is prized by Henrik.

As the executive manager and director of winemaking for Acumen, acclaimed winemaker Henrik Poulsen guides a team dedicated to creating the next great Napa Valley wine estate. With a philosophy deeply rooted in Acumen’s two remarkable estate vineyards, and a winemaking approach that takes its inspiration from the legendary Napa Valley Cabernet Sauvignons of the 1960s and 1970s, Henrik crafts classically structured mountain-grown wines that are recognized for their balance, vineyard-driven complexity and age-worthiness.

Born in Denmark, Henrik was raised in a wine-loving family, and he purchased his first bottle of classified Bordeaux when he was just 14 years old. While attending university in Copenhagen, Henrik found himself falling deeper under wine’s spell. As he began reading books about wine, attending tastings, and working in a local wine shop, he realized that wine was his true path. He soon left school and traveled to Bordeaux to gain hands-on winemaking experience working at Château de Haux. In 2000, after meeting Newton Vineyard Founder Su Hua Newton in Paris, Henrik moved to Napa Valley, eager to gain a more global winemaking perspective. Over the next six years, he immersed himself in the world of Napa Valley wine, while working alongside renowned European winemakers Luc Morlet, and later Jean Hoefliger.

In 2006, following Newton’s purchase by LVMH, Henrik and Jean joined the founding team at Alpha Omega, where they quickly established it as one of the most exciting wineries in Napa Valley. There, Henrik made wines using grapes from some of Napa Valley’s greatest vineyards, including Stagecoach, and Beckstoffer’s To Kalon, Dr. Crane and Georges III vineyards. During his seven years at Alpha Omega, he gained invaluable experience from legendary consultant and master blender Michel Rolland. While at Alpha Omega, Henrik also had the opportunity to explore some of the great Napa Valley wines of the ‘60s and ‘70s.

“Experiencing the great older Napa Valley wines was a revelation,” says Henrik. “I was deeply impressed by their complexity and longevity. It was an epiphany to see many of the qualities I loved about the greatest wines of Burgundy and Bordeaux realized in a uniquely Napa Valley way.” After founding his own Release Winery, and a wine consulting business, Henrik joined Acumen in 2013 as director of winemaking, working alongside founding winemaker—and Château Latour veteran—Denis Malbec. Together, Denis and Henrik established the Acumen style, crafting wines that artfully balance the robust mountain tannins of Atlas Peak with the nuance and complexity of Acumen’s two exceptional estate vineyards.

Today, as both director of winemaking and executive manager, Henrik collaborates with Viticulturist Garrett Buckland and Vineyard Manager Jesus Gonzalez to grow grapes that possess perfect phenolic ipeness, while still retaining complex structure due to their naturally high tannin levels. To tame these robust tannins, in the winery Henrik uses special yeasts, cool fermentations, gentle extractions and ideal cooperage pairings to create silky wines with the structure to reward long-term cellaring. “Our aim is to make wines with an ideal balance between tannin, acid, intensity and fruit;” adds Henrik, “wines that celebrate the character of each new vintage, and the complexity of our Atlas Peak estate vineyards.”

A perfectionist with a gifted palate and meticulous attention to the details that define great winemaking, José Rodriquez joined the Acumen team as cellar master in 2013 and was quickly promoted to assistant winemaker the following year. Today, after a career spent learning from such winemaking luminaries as Jean Hoefliger and the late Denis Malbec, José oversees the day-to-day winemaking at Acumen, while working in collaboration with Winemaker Henrik Poulsen to create classically structured mountain-grown wines from Acumen’s acclaimed Edcora and Attelas vineyards.

A native of Napa Valley, José’s mother and father both worked in the vineyard management industry, giving him a deep understanding of the thoughtful viticulture required to make exceptional wines. José began his winemaking career in 2006, when he joined the founding team at Alpha Omega, along with Winemaker Jean Hoefliger and then-Assistant Winemaker Henrik Poulsen. In addition to being able to hone his craft working with Jean and Henrik, Jose had the opportunity to craft wines from some of Napa Valley’s most revered vineyards, including Stagecoach, Beckstoffer’s To Kalon, Dr. Crane and Georges III. Eager to gain a more global winemaking perspective, José also traveled to South Africa to work a harvest at Rupert & Rothschild Vignerons—the acclaimed partnership between Bordeaux’s Rothschild family and vintner Dr. Anton Rupert.

In 2013, José left Alpha Omega, along with Henrik, to join the Acumen team as cellar master. There he embraced the collaborative spirit of the winery and its vision for establishing a new benchmark on Atlas Peak. After a year spent working alongside Henrik and then-Winemaker Denis Malbec, José was promoted to assistant winemaker. “I love the challenges and rewards of working with great mountain fruit,” says José. “There is a level of power and intensity that it is almost impossible to achieve on the valley floor, but when you understand how to tame the tannins, the wines have balance, beautiful structure, and an underlying elegance.”

In addition to his role at Acumen, José has been a member of the St. Helena volunteer fire department for more than two decades, where he currently serves as captain. He lives in St. Helena with his wife, Veronica, and his young son, José Jr. 

In the world of winegrowing, Garrett Buckland is recognized as a viticultural master known for elevating the quality of already exceptional sites to Grand Cru-caliber vineyards, while cultivating some of the finest grapes in the world. Born and raised in Napa Valley, Garrett is a second generation viticulturist, who honed his craft working at his father’s Buckland Vineyard Management. In the years since, Garrett has helped to steward some of Napa Valley’s most renowned vineyards, including Araujo, Dalla Valle, Realm, Knights Bridge and Hall, and in 2016, he was elected president of the Napa Valley Grapegrowers association. Since 2012, Garrett has applied his decades of winegrowing experience and viticultural knowledge to the care of Acumen’s vineyards on Atlas Peak, with the goal of establishing them as Napa Valley’s next great wine estate.

The son of noted viticulturist Al Buckland, Garrett learned to drive a tractor when he was four, and spent his summers working for his father’s vineyard management company. While studying viticulture and enology at UC Davis, Garrett gained additional experience at both Foundation Plant Services and the Department of Plant Pathology. After earning his degree, he spent the next seven years as the winemaker for Perry Creek Winery, during which time he also cofounded Premiere Viticultural Services. Adding to his encyclopedic knowledge of winegrowing, Garrett is also a partner at VineInfo, a vineyard software company and viticultural database for ultra-premium winegrowers.

In 2012, when Eric Yuan set out to establish Acumen in Napa Valley, he sought out Garrett’s expertise in selecting Acumen’s vineyards. Searching for the ideal terroir to make beautifully structured wines of uncommon depth and purity, Garrett guided Eric to the high-mountain slopes of Atlas Peak. There, with temperatures often 10 degrees cooler than on the valley floor, the grapes ripen slowly, yielding wines of dazzling charm and purity. After helping to evaluate and select Acumen’s Attelas and Edcora vineyards, Garrett stayed on at Acumen, and has guided the estate’s viticultural program ever since.

Combining lifelong, hands-on winegrowing and vineyard management experience, with years of winemaking expertise and leading-edge technological know-how, Garrett has earned acclaim as a visionary viticulturist. Since joining the Acumen team, he has dedicated himself to coaxing the full potential from the Attelas and Edcora vineyards, through replanting with elite clone and rootstock materials, and the use of state-of-the-art soil preparation methods, trellising, irrigation techniques, diagonal row orientations, and more. In keeping with Acumen’s commitment to the environment, Garrett also oversaw the conversion of both vineyards to organic farming, which resulted in organic certification in 2016.

“Because of how remote it is, and the cost and difficulty of growing grapes here, Atlas Peak has long been a diamond in the rough,” says Garrett. “Working with Vineyard Manager Jesus Gonzalez and his talented team, we are giving every acre of vines at Attelas and Edcora an average of almost 300 hours of handwork each vintage. This is an almost unheard of level of care, and the diamond is starting to shine. Acumen’s estate vineyards on Atlas Peak will one day be considered among the world’s finest.”

Many top wineries have turned to Buckland for his expertise in planting or managing their vineyards, including Araujo, Warren Winiarski, Realm, Knight’s Bridge, Baldacci Family and Kathryn Hall. He has a degree in viticulture and enology from U.C. Davis and serves as president of the Napa Valley Grape Growers.

As the vineyard manager for Acumen, growing winegrapes is more than just a job for Jesus Gonzalez; it is his calling. “I live here on Atlas Peak with my family, and walk or ride my horses, Cabernet and Diablo, through the vineyards every day. I feel the energy from the vines. Plants are like people. To be healthy, they need happiness and balance in their lives. On a weak vine, you need to lighten its load and help it become strong. When you do this, it can produce great things.”

Born in Michoacán, Mexico, Jesus learned to drive a tractor at the age of ten and moved to the United States at 15. In the three decades since, Jesus has earned a reputation as one of Napa Valley’s most skilled and passionate vineyard managers, having helped to oversee the planting of hundreds of acres in Napa Valley, and the farming of thousands. “When I first started working in vineyards, I did it to survive, but today I do it because it is the thing I love.” Jesus guides his team, which includes the 2018 Napa Valley pruning champion, with the same sense of appreciation. “I try to be fair and honest, and every day, we all sit down and share lunch together surrounded by the vineyard. When you have a happy crew, you have a happy vineyard, and that is something you can taste in the wine.” As part of his commitment to his team, Jesus was thrilled to oversee the conversion of Acumen’s estate vineyards to organic farming. “When you farm organically, you see how much life there in the vineyards. I am proud to help guide this beautiful little piece of Napa Valley, and to help create grapes that become wines you can share with family and friends.”

As the daughter of vintners, the sister of a winemaker, and a wine country native, Diana Schweiger brings a rare and unique skillset to Acumen—expertise that has been honed over the course of more than 25 years in the wine industry. As the sales and marketing director for Acumen, Diana views her role as a homecoming of sorts. “I spent years working alongside my family to build something special from the ground up on the slopes of Spring Mountain,” says Diana. “What we are striving to achieve here on Atlas Peak is very similar. It’s driven by our remarkable estate vineyards, a love of farming, and a commitment to crafting some of the world’s finest mountain-grown wines. I take incredible pride in being able to introduce this region, and its beautifully complex Cabernet Sauvignons to wine enthusiasts.”

Diana grew up in a home where wine was embraced as part of the fabric of family life. This connection only deepened when her family planted their first grapes on Spring Mountain in 1981, establishing Schweiger Vineyards. After earning degrees in both public relations and marketing from California State University, Chico, Diana began her career at Heublein before moving on to Paterno Imports, where she was the West Coast regional manager, and later Southcorp Wines, where she served as Western regional manager. In 2003, after more than a decade of working for some of the most respected wine companies in America, Diana brought her talents to her family’s winery as vice president of sales. 

“My time at Heublein, Paterno, and Southcorp was like earning a master’s degree in sales and marketing,” says Diana. “It was exciting to apply that experience to my family’s winery.” Over the next dozen years, Diana helped to establish Schweiger Vineyards’ reputation for making exceptional mountain wines, while building a dynamic and successful sales program. In search of new challenges, Diana joined the Prestige Beverage Group in 2016, before being named the national sales manager for Fort Ross Vineyard & Winery the following year. There, she was able to triple the number of markets the winery was in while launching new brands and earning access to some of the most coveted wine lists in America.

In 2019, Diana returned to her mountain winery roots, when she joined Acumen as sales and marketing director. Working with Founder Eric Yuan and Estate Director Mark Castaldi, Diana is dedicated to establishing Acumen as Napa Valley’s next great wine estate. To achieve this goal, she applies a relationship-driven approach to her role in guiding sales and marketing and overseeing the winery’s DTC and wine club programs. “As a small, family-owned winery, Acumen has such a clear and exciting vision, and the values to achieve it. From the amazing team we’ve brought together to our commitment to organic farming to our belief in crafting mountain wines that authentically reflect the beauty and complexity of our terroir, we are creating something that will endure for generations.”

In addition to her extensive industry experience, Diana has served as a wine competition judge, a spokesperson for Napa Valley Vintners, and is a current member of Women of the Vine. She lives in St. Helena with her two teenage children.

In 2014, Laura Hudson became Acumen’s fourth employee, and in the years since she has become an indispensable part of the team, helping to oversee finance, human resources, payroll, and daily operations. In addition to these important duties, Laura works closely with both Acumen’s vendors and the prestigious wineries that source grapes from Acumen’s acclaimed Edcora and Attelas estate vineyards.

Born and raised in North Carolina, Laura developed a deep appreciation for nature and agriculture at an early age. After earning a bachelor of science degree in biology from UNC Charlotte, Laura worked as an administrative manager and senior client care specialist, before serving as a real estate broker for Keller Williams Realty. Utilizing her extensive experience in operations, project management, customer service, vendor relations, and e-commerce systems, Laura joined the team at online golf retailer Kingdom59.com as operations manager and moved to Napa Valley in 2012.

A self-described “country girl at heart,” Laura quickly fell in love with the pace and beauty of wine country, and the world of fine wine, and in 2014, she became the office manager for Acumen. “Working alongside our amazing team to help build Acumen from the ground up is the most exciting and inspiring work I’ve ever done. I spend my days surrounded by the beauty of our vineyards, and collaborating with passionate people, to create something unique and enduring here on Atlas Peak. It is incredibly fulfilling.

In her free time, Laura loves to hike, garden and exploring new parts of wine country and new parts of the world. In recent years, Laura and her husband have traveled throughout France, Australia, and Iceland.
